具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
在复杂的系统中，利用开发模块可插拔的机箱，可根据需求设计各种模块(插卡)。其中，插卡可通过系统背板(backplane)连接在一起。然而，随着通信设备的通信量增大，插卡数量也相应增加。如果系统背板尺寸过大，将无法控制通信设备的机箱的尺寸(宽度、高度)，系统设计困难。
如图1和图2所示，图1是本申请一实施例示出的一种线缆背板系统的结构示意图；图2是本申请一实施例示出的一种线缆背板系统的平面图。本发明示例的线缆背板系统100包括：框架1、以及线缆单元2，该线缆单元2固定于框架1上。该线缆单元2包括：固定于框架1的第一连接器阵列，第一连接器阵列中同行的第一连接器22用以与第一插卡连接；固定于框架1的第二连接器阵列，第二连接器阵列中同列的第二连接器23用以与第二插卡连接；连接第一连接器阵列和第二连接器阵列的通信线缆21。
在发明的实施例中，第一连接器阵列为多个横向及纵向规则排布的第一连接器，同样的，第二连接器阵列为多个横向及纵向规则排布的第二连接器，例如：第一连接器阵列为6×6的组合，第二连接器阵列也为6×6的组合。本发明一实施例的图示中，第一连接器阵列和第二连接器阵列均以矩阵为例进行展示。当然，在本发明的其他实施例中，根据设备的空间需求，该第一连接器阵列和第二连接器阵列也可以为任意规则形状的阵列，或者为非规则的排列阵列。
在本发明示例中，通过通信线缆21，规则地或者任意地连接第一连接器22与第二连接器23，这样，基于通信线缆21的连接，可建立第一插卡和第二插卡之间的通信。例如，第一插卡上的连接器成一行设置，当该第一插卡横向设置在背板上，第一插卡上的每个连接器与同 行的一个第一连接器22对应连接；第二插卡上的连接器也成一行设置，当第二插卡纵向设置在背板上，第二插卡上的每个连接器与同一列的一个第二连接器23对应连接。其中，每个第一插卡通过通信线缆21连接于对应的第二插卡。
在一示例中，第一插卡为业务板卡，第二插卡为交换板卡，如此设置以使用户根据业务扩展需求，可以在通信设备上增加业务板卡时，不需要相应增加交换板卡，易于实现通信设备的可扩展性。同时该通信线缆21可利用高速特性解决了高速链路SI(Signal Integrity，信号完整性)性能问题。在其他实施例中，该第一插卡还可以为内存插卡，第二插卡还可以为网卡等。
如图3所示，在本发明的一实施例中，第二连接器阵列的列数等于第一连接器阵列的列数，且在同一列中，第一连接器22的数量与同一列的第二连接器23的数量相等，这样，在同一列中，第一连接器22和第二连接器23一一对应连接。该实施例中，在第一连接器阵列与第二连接器阵列中，位于同一列上的第一连接器与第二连接器分别一一对应连接，有利于了解第一连接器与第二连接器之间的连接关系，而且有利于管理员对通信线缆的管理及维护。
通信线缆21包括多条线缆，即多条线缆构成了通信线缆21，通信线缆21连接第一连接阵列与第二连接器阵列，每条线缆用于连接第一连接器和第二连接器。在一示例中，在同一列的第一连接器22和第二连接器23中，分别以相邻的所述第一连接器和所述第二连接器为起点，第一连接器22和第二连接器23依次通过线缆连接。例如：四行第一连接器22与四列第二连接器23，同一列的第一连接器22由上至下标记为1～4，第二连接器23由上至下标为5～8，其中，4号第一连接器22与5号第二连接器23相连，3号第一连接器22与6号第二连接器23连接，2号第一连接器22与7号第二连接器23连接，1号第一连接器22与8号第二连接器23相连。在该实施例中，每个线缆呈U型设置，如此设置以使线缆单元2规则排布，通信线缆21在通信设备的横向或者纵向均具有散热通道，避免杂乱的排布方式遮挡住通信设备的散热风道且不利于对通信设备的管理(难于梳理各个连接器的连接关系)。
当第二连接器阵列的列数等于第一连接器阵列的列数，且同一列的第一连接器22的数量为第二连接器23的数量的M倍时，M个第一连接器22通过通信线缆21并线连接于同一第二连接器23，其中，M为大于1的自然数。在一实施例中，如图4所示，以M为2为例进行展示。
当第二连接器阵列的列数等于第一连接器阵列的列数，且同一列的第一连接器的数量与第二连接器的数量不相等时，可以一个第一连接器连接于多个第二连接器或者多个第一连接器连接于一个第二连接器。当然，在本发明的其他实施例中，也可以第一连接器与第二连接 器任意配合连接。例如：多个第一插卡对应的第一连接器构成多个第一连接器组，第一连接器组包括每个第一插卡对应的第一连接器中的一个第一连接器，各个第一连接器组中，位于同一行中的多个第一连接器各不相同，第一连接器组中的第一连接器与对应同一列的第二连接器一一对应连接。
如图2和图5所示，在本发明的又一实施例中，第二连接器阵列的列数大于第一连接器阵列的列数，该第二连接器阵列包括与第一连接器阵列的列数相等的基础列、以及扩展列。多出的至少一列第二连接器23用以与扩展的第二插卡102相连，如此设置可以加快了数据处理速度及增加了数据处理量，可以减缓第二插卡102处理数据交换的压力。本实施例中第二插卡102的数量可以根据第一插卡101的需求数量进行增加或减少，可以实现更好的系统弹性，避免资源浪费。
具体的，如图6所示，图示为一行第一连接器22与一行第二连接器23的连接器剖析图，其中，第一连接器22的数量小于第二连接器23的数量，本实施例以3个第一连接器22转4个第二连接器23为例详细阐述。第一连接器22的信号引脚排线数量多于第二连接器23的信号引脚排线的数量，其中，第一连接器22的一部分信号引脚排线通过线缆中的信号线分别与对应的第二连接器23中的信号引脚排线一一对应连接，该行中每个第一连接器22多余的信号引脚排线则通过线缆中的信号线连接于扩展列的第二连接器22中对应的信号引脚排线，如此设置以满足第一连接器22和第二连接器23之间信号传递的完整性，而且有利于降低线缆单元交工的难度。当然，本发明中并不限于3个第一连接器22转4个第二连接器23的情况，可以根据设计需求，设计任意数量的第一连接器22与任意数量的第二连接器23相连，也包括第一连接器22的数量大于第二连接器23数量的情况，其中，需要满足第一连接器22中的信号引脚排线与第二连接器23中的信号引脚均配合连接且满足信号互通。
由于交换板卡具有尺寸过大、加工难度高、高速链路过长、布线难度过大等问题，因此本发明中增加第二连接器扩展列以降低交换板卡(第二插卡)的设计难度。例如：交换板卡与业务板卡数量相同时，每个业务板卡上需要放8个芯片，当设计6个交换板卡时，总共需要48个芯片，而当交换板卡大于业务板卡(例如8个交换板卡)时，可以每个交换板卡上设置6芯片，就可以达到48个芯片，这样可以使交换板卡上减少芯片数量，更易于交换板卡的设计。
当第二连接器阵列中的第二连接器的列数大于第一连接器阵列中的第一连接器的列数时，第二连接器阵列可以分为基础列和扩展列。其中，基础列可包括与第一连接器阵列数目相同的列，扩展列可包括第二连接器阵列中的其它列。如图2所示，第一连接器阵列中包含 6列第一连接器，第二连接器阵列中包含8列第二连接器。第二连接器阵列包括6列基础列和2列扩展列。如何设置第二连接器阵列中的基础列和扩展列在本申请中不做限定。在本实施例中，通信线缆21包括第一线缆组211和第二线缆组212，每个线缆组包括多条线缆。在一示例中，在同一行中的第一连接器22分别连接于另一行中的第二连接器23时(即实现一个第一插卡101连接于每个第二插卡102)，第一连接器22通过第一线缆组211中的线缆连接于第二连接器基础列中的第二连接器23，通过第二线缆组212中的线缆连接于所述第二连接器扩展列中的第二连接器23。该实施例中，通过将第一连接器22和第二连接器23相连的通信线缆21分线连接至扩展的第二连接器23，以实现第二插卡102数量的扩展。通信线缆21采用该种布局方式，不仅可以使各个连接器之间的连接满足数据交互的需求，与各个连接器之间的连接关系清晰，而且使同一列线缆之间构成了散热通道。
如图2和图7所示，为了使通信设备可以配置更多数量的第一插卡101，至少两行的第一连接器22通过通信线缆21并线分别连接于另一行中的第二连接器23。本实施例中，多个第一连接器连接于一个第二连接器时，为了满足信号传递的稳定性，第二连接器的信号引脚排线数量多于第一连接器的信号引脚排线数量，第二连接器的体积大于第一连接器的体积。在一示例中，可以使通信线缆21的各个线缆均呈U型设置，且相互之间无交叉影响，如此可以使通信线缆21在横向和纵向均具有散热通道。
其中，相邻两列第一连接器之间的间距大于相邻两列第二连接器之间的间距，第一线缆组211中的线缆折弯连接于第二连接器阵列中的基础列与第一连接器阵列；第二线缆组212中的线缆弯折连接于第二连接器中的扩展列与第一连接器阵列。在一示例中，该第一线缆组211中的线缆连接于同一列的第一连接器22时，以相同的第一弯折角度弯折，该第二线缆组212中的线缆连接于同一列的第二连接器23时，以相同的第二弯折角度弯折，以使线缆规则布局，便于对线缆的管理。
当然，在其他实施例中，也可以通过任意连接的方式来实现，需要满足第一插卡与每个第二插卡通信连接，第二插卡与每个第一插卡连接。
如图8至图10所示，在本发明的又一实施例中，该线缆背板系统100包括两个第一连接器阵列，第二连接器阵列位于两个第一连接器阵列之间，第二连接器阵列与两个第一连接器阵列分别通过通信线缆21连接。其中，第二连接器阵列也划分为两部分，两部分第二连接器阵列分别与两个第一连接器阵列通过通信线缆21对应连接。具体的，例如：如图8所示，第一连接器阵列101_1为六行，另一第一连接器阵列101_2也为六行，中间的第二连接器阵列中每列具有十二个第二连接器23，其中，同一列的上方六个第二连接器23与同一列中上组 第一连接器阵列中的第一连接器22一一对应连接，同一列的下方六个第二连接器23与同一列中下组第一连接器阵列中的第一连接器22一一对应连接。
如图10和图11所示，在本发明示例中，框架1包括与第一连接器22配合连接的第一结构件11，线缆单元通过第一连接器22配合连接在第一结构件11上而固定于框架1。该实施例中，第一结构件11可以与框架主体一体成型，也可以通过螺钉、铆钉等固定于框架主体。
该第一结构件11包括结构件本体111，以及设置于结构件本体111上的连接孔112，该连接孔112用以与第一连接器22连接。当然，在其他实施例中，该连接孔112也可以为其他结构与第一连接器22配合连接，如：连接件、卡接结构等。
第一连接器22包括第一连接器本体221，分别于第一连接器本体221的上下两侧延伸出的凸台222，该凸台222与连接孔112配合以使第一连接器22连接于第一结构件11。具体的，凸台222固定在该连接孔112上。
再次参照图10和11，一实施例中，该凸台222包括基板222a、设置于基板222a上的螺柱2221。第一结构件11还包括配合于连接孔112以与螺柱2221配合连接的螺钉224。其中，通过螺柱2221穿过第一结构件11的连接孔112，直接与螺钉224固定连接，以使螺钉224与第一连接器22的凸台222将第一结构件11夹持住，从而实现第一连接器22的连接。
其中，螺柱2221的高度大于连接孔112的孔深度，即螺柱2221的高度比第一结构件11的料的厚值大，如此设置以使第一连接器22可以在第一连接器22与第一结构件11的相对方向上移动，即为第一连接器22设计了一定的浮动量，以便更好地吸收结构公差。在一示例中，可以通过更改第一结构件11的料厚来调整第一连接器22的在第一连接器22与第一结构件11的相对方向上的浮动量。
进一步的，该螺柱2221的外直径小于连接孔112的孔直径，如此通过连接孔112的孔径和螺柱2221的轴径差值来实现间隙配合，使第一连接器22可以满足在螺柱2221径向上的浮动量。在一示例中，如果发现第一连接器22的浮动量设计不合理，直接更改第一结构件11的连接孔112直径即可调整浮动量，而不需要对第一连接器22进行更改，因为第一结构件11的变更比第一连接器22的变更更容易实现。
如图12所示，又一实施例中，该凸台222包括基板222b，设置于基板222b上的凸起2223，设置于凸起2223自由端的限位部2224，该凸起2223中空设置。其中，凸起2223的外直径小于连接孔的孔直径，限位部2224外直径大于连接孔的孔直径。在该实施例中，凸起2223中空设置以使该凸起2223具有弹性，在与第一结构件装配时，通过外力压缩凸起2223的自 由端以使限位部2224限缩至可以穿过连接孔，当限位部2224穿过连接孔时消除外力，此时限位部2224在弹力作用下恢复至初始状态，此时第一结构件被限制在限位部2224与基板222b之间，从而完成第一连接器22与第一结构件的装配。
本实施例中，限位部2224可以为倒棘，如此设置以使该限位部2224的周测具有引导斜面，以便于第一连接器与第一结构件的插接，更加易于装配。其中，凸起2223的外直径小于连接孔的孔直径，以通过连接孔的孔径和凸起2223外直径的差值来实现间隙配合，使第一连接器可以满足在凸起2223径向上的浮动量。另外，还可以使第一连接器在凸起2223的轴向上设置有一定的浮动量，以便更好地吸收结构公差。
如图2、图13和图14所示，框架1还包括与第二连接器23配合连接的第二结构件12，线缆单元通过第二连接器23配合连接在第二结构件12上而固定于框架1。该第二结构件12包括具有容纳空间的金属外壳121，设置于金属外壳121一侧的卡接部122，以及设置于金属外壳121另一侧的连接部123，该连接部123和卡接部122分别位于金属外壳121的相对两侧。其中，第二连接器23通过该金属外壳121固定于框架主体，具体的，在第二结构件12通过卡接部122与框架主体配合卡接后，再通过连接件配合连接部123将第二结构件12固定于框架主体。这种装配方式可以最大限度地节约第二连接器23在框架1上的装配空间，通过一个连接件配合连接部123以及一个卡接部122可以实现多个第二连接器23的装配。该实施例中，连接部123采用螺钉。
金属外壳121的容纳空间可装配多个第二连接器23，多个第二连接器23固定在金属外壳121内，固定在金属外壳121内的多个第二连接器23与同一第二插卡配合插接。第二连接器23包括第二连接器本体231，卡配于第二连接器本体231上的弹片232，以及设置于第二连接器本体231底部的凸起部233。其中，第二连接器本体231与容纳空间之间具有间隙，第二连接器本体231通过弹片232卡接在间隙而使第二连接器本体231固定于金属外壳121上，该弹片232的弹性属性使得第二连接器本体231相对金属外壳121具有浮动量。
进一步的，该弹片232包括向外弯折延伸出的止位部2321，其中，当第二连接器23安装于金属外壳121的容纳空间内，凸起部233配合于金属外壳121的槽孔，止位部2321抵持于金属外壳121的上端面。该第二连接器23通过凸起部233的特征及止位部2321的特征实现了该第二连接器本体231与金属外壳121在装配方向上的限位且具有浮动量。
在本实施例中，该第二连接器本体包括围合成框架结构的壳体、设置于该壳体内的多个弹片引脚。在一示例中，多个弹片引脚平行设置。当多个第一连接器连接于一个第二连接器时，第一连接器的弹片引脚数量明显小于第二连接器的弹片引脚数量，第二连接器的体积也 大于第一连接器的体积。
本发明示例中，设计了一种线缆背板系统100，简化了背板设计的复杂度，而且可以满足通信量增大的需求，利用线缆背板系统100中通信线缆21高速特性解决了高速链路系统信号完整性的性能问题，该线缆背板系统100还可以减小系统背板的尺寸，同时保证了第一插卡的可扩展性。
如图10所示，根据本发明实施例的又一方面，还提出了一种通信设备200，该通信设备200包括：设备机箱201，如上述所描述的线缆背板系统100，多个第一插卡101，以及多个第二插卡102。其中，第一插卡101与线缆背板系统100中同行的第一连接器22连接，第二插卡102与线缆背板系统100中同列的第二连接器23连接。
线缆背板系统100中的框架1固定于设备机箱201，以使整个线缆背板系统100固定于设备机箱201内。当然，该框架1也可以为设备机箱201的一部分，与设备机箱201一体成型设置。
具体的，第一插卡101和第二插卡102上的连接器都成一行设置。当第一插卡101和在第一插卡101和第二插卡102分别与第一连接器阵列和第二连接器阵列连接时，第一插卡101上的连接器与第一连接器阵列上一行的第一连接器22配合插接，第二插卡102上的连接器与第二连接器阵列上任一列的第二连接器23配合插接。在本发明一示例中，该第一插卡101为业务板卡，第二插卡102为交换板卡，多个业务板卡之间通过多个交换板卡相互通信。
如图8至10所示，在本发明的一实施例中，与线缆背板系统100中第一连接器阵列和第二连接器阵列的一实施例布局相对应，多个第一插卡101分为两组，多个第二插卡102位于两组第一插卡101之间；其中，第二插卡102通过线缆背板系统100中分别连接于两组第一插卡101。该实施例中，将通信设备中第二插卡102分别与两组第一插卡101单独连接，两组第一插卡101通过第二插卡102实现各个第一插卡101的信息交互，第二插卡102位于中间，可以实现缩短线缆单元2中线缆的长度。
如图2和图7所示，在本发明的又一实施例中，该第一插卡101和第二插卡102上下分布，其中，第一插卡101的数量可为第二插卡102上的连接器的数量的N倍，同一列N个第一插卡101上的连接器与第二插卡102上对应的连接器通过线缆背板系统100中的线缆单元2连接；其中，N为大于1的自然数。如此设置可以大幅减小通信设备的尺寸，且可以配置更多的第一插卡101，进而增加通信设备的业务处理能力。
进一步的，该通信设备还可以通过增加第二连接器阵列的列数以增加第二插卡102的数 量，通过增加第二插卡102增强了通信设备的业务处理能力，并且加快了业务处理速度，同时可以满足通信设备配置更多的第一插卡101。
本发明设计了一种线缆背板系统及通信设备，利用高速线缆实现了业务板卡与交换板卡连接的设计方案，可以提高数据交互速度，通过线缆单元布局特点，实现线缆背板系统的灵活配置，满足业务板卡和交换板卡更多的配置需求；具有该线缆背板系统的通信设备则拥有更强的业务处理能力，可扩展性增强，满足用户对业务板卡和交换板卡的多种配置需求，具有更佳的市场竞争力。
